Do not use pipe sealant (dope), as solvents in some types of pipe dope may cause damage to plastic fittings. Do not overtighten, overtightening can cause damage to filter head.

5. Install Whirlpool Grounding Kit WHKF-GRND (see Figure 3) in metal water piping systems.
IMPORTANT: Metal water piping systems are required to be connected to the electrical ground. To maintain the ground connection, obtain kit WHKF-GRND by contacting location where filter head was purchased. Ground Kit Installation:
a. Install one ground clamp on the incoming metal water pipe section and one on the outgoing metal water pipe section. Be sure that the filter head, fittings and valves are between the two ground clamps.
b. Connect the ground wire to the two ground clamps, using the wire screw terminal on each grounding clamp. Tighten securely.
